Help! Not been for 5 days I think maybe more and I now feel really sick and haven't managed to eat much today. I have taken ducolax, lactose and a senna and none of them are working. Have taken 3 doses of lactose last night and today. Drank coffee, ate some chocolate but not working. Drank lots of water today. Now feeling uncomfortable. Pharmacy closed here on a Sunday. Any other otc suggestions I can get from a supermarket? Or home remedies please. Thanks
